Structures Flashcards
Science
Internal Forces
A force that comes from withen the structures.
External Forces
A force that comes from outside the structure.
Centre Of Gravity - What does it do and what is it?
The imaginary point in a structure where it’s mass is concentrated. Centre of gravity helps with stabilazation.
Structural Materials - components
Arches, beams, truss, columns
Structural Materials - shapes
Beams, anges, channels, plutes
Structural Materials - materials
When creating a structure, you have to think about what materials fit the structure best depending on the function.
Newtons First Law
Things in rest will stay at rest. Things in motion will stay in motion.
Structural Failure - why structures fail
- Bad design
- Faulty construction
- Extreme conditions
- Foundation failure
Structural Failure - stress
Temporary signs of stress.
Structural Failure - fatigue
To much force is placed on the structure.
Structural Failure - failure
Breakdown of a structure due to external and internal forces acting on it.
Factors in designing structures - aesthetics
How it is viewed.
Factors in designing structures - market research
Gather and evaluate data.
Factors in designing structures - cost effective
Produces good results without costing a lot of money to make.
Factors in designing structures - lifespan
Life expectancies.
